This study assesses historical conditions and landscape change in the southern part of the Santa Clara Valley. It is designed to inform strategies for natural flood protection, habitat conservation and restoration, and other management challenges. The project area is the valley floor of southern Santa Clara County (south of Morgan Hill) and northern San Benito County (the Soap Lake floodplain north of Shore Road) and includes the lower Uvas-Carnadero, Llagas and Pacheco creeks as well as the Pajaro River.

Along with research completed in the Coyote Creek Watershed and current research on western Santa Clara Valley, this project will provide comprehensive coverage of historical habitats for the entire Santa Clara County valley floor.
